Here's how 'Game of Thrones' turns a man into a White Walker

Scott Ian was turned into a White Walker by 'Game of Thrones'' prosthetic designer Barrie Gower. Nerdist/ YouTube While winter is always just "coming," the White Walkers are actually here on "Game of Thrones," and their ice-hardened, scary faces aren't going anywhere.

The HBO show's Emmy-winning prosthetic designer Barrie Gower demonstrated the complexity of the process it takes to turn an actor (actually, a stuntman) into a White Walker in the Nerdist's latest "Bloodworks" video.

In the video, the band Anthrax's Scott Ian gets the full White Walker treatment. And he's the first American to become a White Walker.

Even with the level of difficulty required, Gower says in the video, "'Game of Thrones,' for a prosethics artist, is like a bucket list basically."

Gower explains that the inspiration for the White Walkers' look initially came from another popular show, "The Walking Dead." But, of course, "Game of Thrones" created its own approach for its fantasy world's zombies.

To achieve the White Walkers' distinct skeletal qualities, Gower says the makeup artists block out the primary forms of the face before adding in texture.

Ice, marble, and crystal are some of the inspirations for the paint job, though Gower also describes some of the Walkers' features as "wrinkly" and "elderly."

The prosthetic might look stiff, but Ian says it's quite "malleable."

While the White Walkers and Wights might cause unecessary panic among viewers, knowing their names might make them seem more approachable. Gower says they are named after their actors or stuntmen, so they could be called Vlad, Harold, or even Chris.

At least Ian's Walker isn't so scary.
